Gen Z B2B buyers are no longer the junior researchers on the deal. Together with millennials they made up 71% of B2B buyers in Forrester's 2023 Buyers' Journey Survey, and they bring consumer psychology into every business purchase. Most B2B marketing is still built for a buyer who retired from the committee years ago. This post lays out the evidence and what to do about it.
Key takeaways
Millennials and Gen Z made up 71% of B2B buyers in Forrester's 2023 Buyers' Journey Survey, up from 64% the year before.
67% of B2B buyers now prefer a rep free experience, up from 61% a year earlier, according to Gartner surveys published in 2025 and 2026.
90% of millennial and Gen Z buyers report dissatisfaction with vendors in at least one area, against 71% of older buyers, per Forrester.
Only about 5% of your category is in market in any quarter, per Ehrenberg-Bass research for the LinkedIn B2B Institute, so brand memory decides who makes the shortlist.
The practical move: treat your launch like a consumer moment, not an announcement, and build memory in the 95% who are not buying yet.
Why does this matter now?
Because the buyer changed faster than the marketing did. Forrester reported that millennials and Gen Z crossed from 64% of B2B buyers in its 2022 survey to 71% in 2023. The people approving your contract grew up with Amazon reviews, TikTok search and one tap checkout, and they judge your six week procurement flow against that standard.
They are also harder to please. Forrester found that 90% of younger buyers report vendor dissatisfaction in at least one area, compared with 71% of older buyers. The gap is not product quality. It is the buying experience itself.
What the research shows
Method note: this piece is a literature review of named third party studies, cross checked against the original publishers. Four findings matter most:
The majority flipped. Millennials and Gen Z are the majority of B2B buyers: 64% in 2022, 71% in 2023 per Forrester's Buyers' Journey Surveys.
They do not want your rep. Gartner found 61% of B2B buyers preferred a rep free buying experience in 2025, rising to 67% in its 2026 survey of 646 buyers.
They research where you cannot see. Forrester expected more than half of large B2B purchases to run through digital self serve channels in 2025, with younger buyers leaning on social media and their own networks, and half of younger buyers pulling 10 or more external influencers into a purchase.
Almost nobody is in market. Professor John Dawes at the Ehrenberg-Bass Institute, in work for the LinkedIn B2B Institute, showed roughly 95% of category buyers are not in market in any given quarter.
Why do Gen Z B2B buyers behave like consumers?
Because the brain does not switch modes when it opens a work laptop. A buyer who checks reviews before a £30 purchase does not stop checking them before a £30,000 one. Gen Z B2B buyers apply the same heuristics at work that they use as consumers: peer proof over vendor claims, self serve over sales calls, and short video over whitepapers. The Gartner rep free numbers above are not laziness. They are a trust strategy learned from consumer markets, where the seller who insists on a phone call is usually hiding the price.
Where do younger buyers actually research vendors?
Mostly in places your attribution software cannot reach. Forrester's 2025 predictions flagged that younger buyers rely on external sources, including social media and their value networks, to make buying decisions. That means Slack and WhatsApp communities, LinkedIn comment threads, Reddit, group chats and AI assistants. This is the dark social layer: the deal is shaped before you ever see a form fill.
You can watch the brands built for this in the wild. Gong turned a sales analytics product into a personality on LinkedIn. Ramp runs a media style content engine rather than a gated whitepaper library. Cognism rebuilt its demand model around ungated content and dark social, on the logic that the buyer journey happens in channels you influence but do not track. None of these companies waited for attribution to prove it first.
Does the rational B2B buyer still exist?
The fully rational one never did, and the 95-5 rule explains why that matters more now. If only about 5% of your market is buying this quarter, per Ehrenberg-Bass, then 95% of your marketing's job is memory, not conversion. When a Gen Z buyer finally enters the market, the shortlist is written from brands they already know, like and have seen referenced by people they trust. Lead generation harvests decisions that brand and culture already made.
The Ignita insight: your launch is now a consumer moment
Here is the conclusion most B2B playbooks miss. The standard response to the self serve data is to build more funnel: more product led onboarding, more comparison pages, more automation. Useful, but it only serves the 5% already in market. The bigger lever is cultural. A B2B launch in 2026 is judged like a consumer product drop, in the feed, by people who will never book a demo, months or years before they buy.
That changes what a launch is for. It is not an announcement to the in market few. It is a memory injection into the out of market many. The winning launch optimises for being screenshotted, quoted in a group chat and retold in a Slack community, because that is where the 71% now decide who exists. It is the same pattern we unpack in our funding announcement teardowns: the startups that win compress their story into moments the feed can carry.

What founders and marketers should do
Audit your buyer's age. Pull your last 20 closed deals and note the age band of the champion and decision maker. If your messaging assumes a 50 year old procurement lead and your champions are 29, fix the messaging first.
Publish your pricing. Rep free preference is 67% and rising. Hiding pricing behind a call is a trust tax younger buyers will not pay.
Ungate your best content. Dark social does not fill in forms. Let your strongest thinking travel freely and measure lift in branded search and inbound quality instead.
Build for the 95%. Split budget explicitly: a conversion lane for the in market 5%, a memory lane for everyone else. Short video, founder voice and community presence go in the second lane.
Make the founder the face. Younger buyers trust people over logos. A founder posting three times a week beats a brand account posting daily.
Design launches as cultural moments. One sharp narrative, native to the feed, built to be retold. Study how the best AI startups run it in our launch and growth insights.
Instrument what you can, respect what you cannot. Add a "how did you hear about us" free text field to every form. It is the cheapest dark social tracker that exists.
FAQ
What share of B2B buyers are Gen Z and millennials?
71% as of Forrester's 2023 Buyers' Journey Survey, up from 64% in 2022. They are the majority of business buyers, including on high value deals.
Do younger B2B buyers still want to talk to sales?
Mostly no. Gartner found 67% of B2B buyers prefer a rep free experience in its 2026 survey, up from 61% the year before. Sales still matters for complex deals, but buyers want it later and on their terms.
What is the 95-5 rule in B2B marketing?
Ehrenberg-Bass research for the LinkedIn B2B Institute showing about 95% of category buyers are not in market in a given quarter. Marketing that only targets active buyers ignores 95% of future revenue.
How do Gen Z B2B buyers research software vendors?
Through self serve channels, social media, peer communities and AI tools, largely outside vendor controlled channels. Forrester notes younger buyers lean on external sources and bring 10 or more outside influencers into purchases.
Does consumer style marketing actually work in B2B?
Yes, when it builds memory rather than gimmicks. Brands like Gong, Ramp and Cognism grew by borrowing consumer tactics: personality, ungated content and social native formats aimed at buyers who are not yet in market.
How should a startup launch change for younger buyers?
Treat the launch as a memory event for the 95% out of market, not an announcement for the 5% in market. Optimise for shareability in feeds and group chats, lead with the founder's voice, and keep the story simple enough to retell.
